10 CLOCK TIMER
Specifications
Control of clock timer
Vector address setting for clock timer interrupt
(1) rtm_init: Initialization for clock timer
Enables the respective 32 Hz, 8 Hz, 2 Hz and 1 Hz interrupts of the clock timer, clears the timer
data and starts the clock timer. The interrupt level has been set at IRQ1.
(2) rtm32_intr, rtm8_intr, rtm2_intr, rtm1_intr:Clock timer interrupt processing
